Using an $25 Gotek floppy emulator in place of a 8" floppy drive

#gotek #trs80 #refurbish

In the latest installment of the TRS-80 Model II saga, I try to clean up and polish the case of the computer, then reassemble it so I can use it. Then I show how to get a cheap Gotek floppy emulator working in place of a 8" disk drive.

Correction: as people pointed out, they are more expensive than the last time I purchased them -- about $25 as of Jan 2022.
